Metaverse Issues and Challenges

1 The difference between encountering a challenge and encountering a problem

To understand this problem, you must first understand the meaning of two words
Challenge: take the initiative to try to overcome the opponent.
It can also be understood as setbacks and difficulties.
Questions: Questions that require an answer or explanation.
When you encounter a challenge, you need to choose to face it or avoid it. This matter is difficult for itself, and when you encounter a problem, you are faced with a problem. But it is difficult, you need to choose to solve the problem when you encounter a problem.

2 What are the current problems and challenges faced by blockchain-based smart contracts

Jinwowo Group analyzes the problems faced by blockchain-based smart contracts There are the following points:
1-Security issue: One of the key issues is the issue of security and trust. Smart contract systems are designed to be a trustless environment, which means that errors that occur cannot be corrected;
2-Privacy issues: One of the challenges of effectively utilizing blockchain is that blockchain provides complete transparency;
3-Unexpected scenario problem: Smart contracts sound very good, but how to correctly and appropriately handle contract execution in unexpected scenarios is a problem.

⑶ What is “metaverse” and is “metaverse” really a scam?

“metaverse” is not a scam, it refers to a The world is parallel, and at the same time it is an independent virtual space, in other words, it is a real digital virtual world.

“Metaverse” is a very hot topic, many business giants have joined related fields one after another, and have begun to join the “metaverse” industry. Such a seemingly illusory world, as long as it takes time, I believe that the “metaverse” scene will appear in the near future.

I. What exactly is the “metaverse”, a virtual space

“metaverse” is a new type of cyberspace and social form composed of many new technologies , using the mirror image of the real world produced by digital technology, the blockchain technology creates an economic system that combines fantasy and reality, and allows all users to edit its content. The term “metaverse” first appeared in Stephenson’s science fiction novel “Avalanche”, which describes an alternate digital world parallel to the current one, in which everyone in the real world lives. Have another virtual self.

Summary

“Metaverse” is not only not a scam, but also promotes the development of the Internet, making people truly feel the wonder of the digital age through virtual reality equipment. People can enter the virtual space to socialize with colleagues as long as they wear the device, and even use the “metaverse” to create a virtual world. From then on, human beings will become “amphibians” of the real and virtual worlds.

⑷ The difference between challenges and problems

Simply put, there is a noun in front of an attributive clause, that is, an antecedent, and the translation of where is related to the antecedent. Such as the first sentence where can be translated as in the eastern region, the second sentence can be translated as in some regions of the world.
And there is no noun in front of the adverbial clause, the translation is unified as in the place of
I am standing where there was a school. I stood in the place where there was a school. (adverbial clause)
I am standing at the place where there was a school. (attributive clause)

⑹ What problems and challenges does modern society have

Your question is too broad. Try to answer: Equity issues include the distribution of social wealth and judicial justice. I think these two are fundamental. No matter what society, feudal, capital or social, there are classes or strata. The ability and amount of social wealth held by different classes are vastly different. Such as the current Chinese migrant workers and civil servants, business owners (state-owned enterprises and private enterprises). Not suffering from poverty but suffering from inequality. The root cause of social turmoil is often that the lower classes are deprived of their ability to survive, so they have to rise up and resist.

⑺ What are the challenges and problems facing the world

2011 , In view of more uncertainties and new risks emerging, is it widely believed that the world economic recovery will slow down? Comprehensive International Monetary Fund (IMF)? OECD? The forecast of the United Nations and other international institutions, the 2011 worldWorld economic growth will slow to around 4%? Developed countries such as the United States, Japan, and Europe will find it difficult to maintain the current growth rate due to the weakening of the stimulus measures, and at the same time have high fiscal deficits? High unemployment? The private wealth that has not yet recovered will hinder the process of economic recovery. It is expected that the overall economic growth rate in 2011 will be 2%? Due to the further tightening of monetary policy and the gradual withdrawal of fiscal stimulus, the growth momentum of developing countries will also moderate. Overall, the unevenness of the world economic recovery in 2011 will continue to exist, and the instability and fragility of the recovery will become more obvious? Among them, the inflation situation? Sovereign debt risk? Trade protectionism? Exchange rate disputes and capital market volatility will be the five major challenges to the sustained recovery of the world economy? The West may continue to release liquidity to intensify inflation differences. Since the current financial crisis, countries around the world have injected a lot of liquidity into the market? With the gradual recovery of the economy, excess global liquidity begins to emerge, and inflationary pressures accumulate rapidly? Due to the intensified differentiation of economic recovery between developed and developing countries, there are also huge differences in the inflation situation faced by the two camps? In 2011, global inflationary pressure will rise significantly, especially in developing countries? This is due to the fact that the large amount of liquidity injected by developing countries themselves during the crisis has not been fully recovered, so it may continue to push up inflation, and uncertain factors such as natural disasters will also cause the already high price level to continue to rise? On the other hand, could developed countries continue to abuse liquidity? Since the recovery of developed countries in 2011 will still be weak, it is unlikely to withdraw liquidity significantly, and once the economic recovery fails to meet expectations, they are likely to expand the scale of easing policies and inject more liquidity? For our country, inflation pressure has become a major challenge to be considered in maintaining the stable and healthy operation of the economy? In 2011, my country will not only continue to suffer from internal inflationary pressures, but also face more severe imported inflation caused by excess global liquidity and rising commodity prices? Debt risks and policy withdrawals plague economic recovery In 2011, European and American fiscal austerity policies may be difficult due to the economic downturn, and the high fiscal deficits may be difficult to shrink, which will lead to the continued spread of debt risks and the continued rise of risk aversion in the market? In 2010, the budget deficit or public debt level of the 27 EU countries has almost all exceeded the upper limit allowed by the EU. Among them, the Irish budget deficit accounts for 32% of the gross domestic product (GDP), which is more than 10 times the upper limit set by the EU? The U.S. federal budget deficit in fiscal year 2010 was as high as $1.29 trillion, the second-highest level since World War II? The Obama administration had expected the federal budget deficit in fiscal 2011 to reach $1.42 trillion? Under the pressure of the deficit exceeding the standard, European and American countries have begun to promote fiscal austerity policies, and some European countries have been set stricter targets because of external aid? The extremely severe fiscal deficit situation, coupled with the severe austerity task, will pose a greater constraint on the governments of Europe and the United States to continue to stimulate economic growth, resulting in the dilemma of reducing the deficit and avoiding damage to the economic recovery? On the one hand, there is a big risk of spreading the current Irish debt problem, and the euro area countries must implement strict fiscal tightening policies to restore market confidence? On the other hand, austerity means reducing the size of the stimulus plan, which may affect the effect of the stimulus plan and damage the current recovery momentum? At present, the economic recovery of various countries in the world is largely driven by the large-scale economic stimulus plans of various countries, with obvious “policy” recovery characteristics? However, the fiscal stimulus policies introduced during the crisis will expire in 2011, and the current prominent deficit pressure and high debt limit the ability of developed countries to continue to launch stimulus programs? This is a huge test for world economic growth in 2011, and is it possible to bring the current recovery that is not yet solid to a standstill? In addition, it is difficult to grasp the timing of the withdrawal of the stimulus policies of various countries in the world. If the coordination is not good, it will also have an impact on the world economy? At present, the pace of withdrawal of monetary policy in developed countries is generally delayed. International institutions such as the OECD expect that the withdrawal of monetary policy in major developed countries such as the United States has been delayed until after 2012. Will the easing policy be maintained or expanded in 2011? While developing countries have already started to tighten monetary policy ahead of schedule, will further tightening policy be implemented in 2011 under the pressure of inflation? Will the divergence of global monetary policy become more serious? In the future, if the developed countries are uncertain about the timing of their exit, or if there is a lack of coordination among countries with high economic interdependence, will it inevitably bring shocks to the world economic recovery? The momentum of trade protectionism remains unabated In the context of the global financial crisis, is the economic recovery uneven across the world? The competitiveness of industrial and trade structural transformation? Factors such as the polarization of trade distribution interests and the politicization of economic and trade issues are either intensified or amplified, resulting in the intensive outbreak of trade protectionism around the world? 2011 is the worldIn order to protect its own development, the above-mentioned problems will become more prominent in the critical period of whether the world’s economic recovery can be stabilized. It is expected that in 2011, global trade protectionism will present three trends? One is anti-dumping? Countervailing? Will measures such as technology and green barriers become a norm in the formulation of trade protection policies in various countries? As the economic aggregate and influence of developing countries continue to increase, developed countries will increase their concerns about the speed and scale of their development, and will the containment measures to be strengthened? Meanwhile, unemployment is high? Exchange rate fluctuations? Uncertain economic prospects and other factors will promote the rise of protectionist sentiment in the United States and Europe? In addition, not only developed countries such as Europe and the United States have frequently adopted anti-dumping measures against developing countries? Anti-subsidy and other trade protection measures, and trade disputes within developing countries are also increasing. Will international trade protectionism become a “normal” challenge that exporting countries have to face in the future? Second, is the focus of trade protectionism shifting to high-end manufacturing and high-tech industries? Although the advantages of developing countries in manufacturing are still concentrated in labor-intensive products, but the momentum of the shift to high-end products has become very obvious? the economies of developing countries? The adjustment of the industrial structure will cause huge challenges and impacts on the traditional advantageous industries of developed countries. It is expected that the industries in which the two sides have trade disputes will also gradually escalate. Will the focus of international trade frictions shift from general manufacturing to high-end manufacturing? Third, trade protectionism begins to show regional exclusivity? During the financial crisis, Asia? Europe? Economic and trade cooperation within Latin America and other regions has played an important role in getting countries out of the crisis, leading to increased awareness of regional protection? After the crisis, the recovery situation of various regions varies greatly, and global trade agreements such as the WTO Doha Round negotiations have been delayed, which will further provide impetus for deepening regional trade cooperation, and also increase the exclusion of foreign economies. , the intensity of trade protection will increase? At present, the trade protectionism of developed countries towards my country has changed from textiles? The transfer of footwear to chemical products and steel is expected to shift the focus of friction between the two sides to capital or technology-intensive high-end manufacturing in 2011 and beyond? The “exchange rate melee” may continue to ferment. In 2011, the economies of all countries in the world will face the test of whether they can continue to recover. Therefore, all countries attach great importance to expanding exports. In particular, the developed countries in the United States and Europe, which are struggling with recovery, take exports as an important part of driving recovery? However, it has become a common choice to promote exports through the implementation of a weak local currency policy. The exchange rate disputes among countries around the world will continue to ferment on the existing basis around the trend of the US dollar, forming a “exchange rate melee”? From the overall trend, with the gradual implementation or even strengthening of the second round of quantitative easing policy in the United States, as well as the continued implementation of the US government’s export strategy, will the general trend of the US dollar continue to weaken in 2011 not change? Under the condition that the dollar will continue to depreciate, non-US currencies will rise passively in 2011, which will have an impact on the exports of non-US currency countries, among which developing countries will bear the brunt of the impact and be the most severely affected? Since exports are generally the main driving force of economic growth in developing countries, damage to exports will directly drag down the overall economic growth? At the same time, once the local currencies of developing countries appreciate sharply, will the widening of interest rate spreads trigger the influx of hot money, thereby pushing up their already severe inflation situation? In a sense, exports and inflation are the two core factors that determine the economic growth of developing countries. If these two aspects are hit hard, it may drag down the recovery of the entire world economy? It is foreseeable that the expected weakening of the US dollar in 2011 will continue to trigger the fight against the devaluation of the US dollar? In anticipation of slowing economic growth, developed countries such as the European Union have extended unconventional monetary policies, and may follow the example of the United States to further release liquidity in 2011, when the world’s major currencies will fall into a competitive devaluation situation? For my country, is the pressure of RMB appreciation still very great in 2011? Will the United States and other developed countries continue to use the exchange rate issue to win over more countries, and use bilateral and multilateral diplomatic consultation mechanisms to jointly put pressure on China? Could turmoil in global capital markets intensify after a turbulent 2010, including commodities? In 2011, the global capital market, including the stock market, will be more complicated? The inconsistency of the economic policies of the major global economies in the future, as well as the sovereign debt issue that may break out at any time, will make the global capital market face many uncertainties, which will inevitably exacerbate market turmoil? On the one hand, the trend of monetary policy differentiation between developed and developing countries is becoming more and more obvious? Will the excess liquidity caused by the quantitative easing policy in the United States spread inflationary pressures to the world, which will then cause commodity prices and stock markets to rise? At the same time, the entry of imported inflation will allow developing countries to increase the tightening of monetary policy? This “one loose and one tight” policy situation objectively promotes the frequent flow of capital around the world, and the market will inevitably fluctuate? On the other hand, European debtThere is still a risk of spreading the problem. Once the situation deteriorates, the safe-haven demand for the U.S. dollar and U.S. Treasury bonds will increase sharply within a certain period of time, and the U.S. dollar exchange rate will also rebound in stages? The alternating trend of the long-term weakening of the US dollar and the periodic rebound will lead to intensified fluctuations in the prices of commodities denominated in US dollars in the international market, and will be prone to skyrocketing or plummeting? In addition, economic growth is the basic factor affecting the trend of the capital market, and the prospects for the recovery of the world economy in 2011 are still uncertain, with great uncertainty. Once the recovery of major economies comes to a standstill, will the global capital market fall? Due to my country’s strong demand for bulk commodities, excess global liquidity and the depreciation of the US dollar will not only increase the cost of my country’s imports, but also introduce significant inflationary pressures to my country? At the same time, if the international hot money seizes the bad market opportunity to make waves, will it also have an impact on my country’s capital market? (Source: Xinhua News Agency)

⑻ What problems and challenges are facing my country’s opening to the outside world at present

Encountered in opening to the outside world Under the situation of new challenges and new problems, we should not only not shake the basic national policy of opening up, but also strengthen our belief and seek solutions to new contradictions and new problems by expanding opening up.
First of all, going back and stopping is no way out. During more than 30 years of opening up, my country has won unprecedented development and prosperity of an open economy by learning from the world, expanding international economic and trade exchanges, and actively participating in economic globalization. Practice has proved that opening to the outside world is the only way to strengthen the country and enrich the people. The challenges and problems currently encountered are inevitable in the progress, and smooth sailing is just an illusion. If we retreat when we encounter difficulties, we will not only deny our own successful practice of more than 30 years, but also deny the road of socialist modernization. If it stops and the opening to the outside world stops there, not only will it not solve the new problems we are facing now, but it will also lead to a setback in the new situation of an open economy that has been created, and ultimately lead to damage to the socialist market economic system and the cause of socialist modernization.
Secondly, the trend of economic globalization has not changed, and we are still in a period of strategic opportunity that is conducive to opening up. Although affected by the international financial crisis, world trade and international capital flows will decline for a period of time, but the fluctuations of such flows are normal fluctuations in long-term development. The most important thing is that the basic mechanism for promoting economic globalization has not changed, that is: the economic ties and interdependence of countries in the world have not weakened slightly due to the impact of the international financial crisis, but have instead strengthened; dialogue and coordination in the international economy The coordination and restraint role of mechanisms and various multilateral and regional organizations on the world economy is also increasing. Although trade protectionism is on the rise, trade liberalization is still the main trend of the world economy. In the era of economic globalization, each country has me and me in the economy, the intra-company trade of multinational companies accounts for more than 1/3 of the international trade, and the export trade of foreign-invested enterprises accounts for more than 55% of my country’s total export trade. Trade protectionism against trading partners is harmful to both others and oneself; China’s economy may suffer as a result, but it is even more detrimental to the world economy. Therefore, trade protectionism needs to be dealt with seriously, but it cannot become a big climate, so there is no need to worry too much.
The international financial crisis has exacerbated the contradiction between international monopoly capital and the contradiction between international financial oligarchs and the people of various countries, but this contradiction is not enough to cause a world war, and peace and development are still the themes of today’s world. International economic competition and cooperation, reform of the international economic order, and peaceful means of negotiation and mutual compromise are still the main ways and means to resolve these contradictions. Therefore, we are still in a period of strategic opportunity for development, and we must not lose the period of strategic opportunity by giving up opening up. Only by continuing to persist in opening to the outside world and continuously improving the level of opening up can we firmly seize this period of strategic opportunity.
Thirdly, only by continuing to expand opening up can we seize new opportunities to resolve conflicts and improve our ability to manage the development of an open economy. At present, in the face of the difficult situation of declining external demand and international trade and international investment flows, if we stop opening to the outside world and close our doors, we will be really helpless; if we continue to expand opening up, we may find new opportunities in it. and new ways to get out of the predicament. For example, in response to the decline in the growth rate of import and export trade, various efforts such as diversifying the export market, promoting the free trade zone strategy, strengthening international trade financing cooperation, and continuing to promote enterprises to “go global” can be used to resolve difficulties and alleviate the impact of the international financial crisis. Adverse effects; in response to the decline in foreign capital inflows, it is possible to innovate ways of utilizing foreign capital, expand inland and border openings, and realize internal and external openings.We will release measures such as mutual promotion and expanding the use of foreign capital in the service industry to attract foreign investment. There is no complete positive correlation between the scale of foreign investment in my country and the flow of foreign direct investment. The flow of international direct investment has declined for three consecutive years, while the scale of my country’s foreign investment has increased for three consecutive years, with growth rates reaching 14.9%, 12.5% ​​and 1.4% respectively. This shows that the decline of the total international investment flow does not rule out the phenomenon of growth and share of an economy’s flow. The key depends on whether our export commodities and investment environment are competitive.
For the uncertainty of the world economy, we can only gradually understand and grasp its objective laws in the practice of expanding opening up, from knowing little to knowing more. And if you don’t dare to practice, you will always be ignorant. There is of course a price to be paid, but success without a price does not exist. In response to the security issue of my country’s international assets, we not only put forward demands for reforming the international monetary system, but also take practical measures such as currency swaps, regional financial cooperation, and pilot RMB settlement for cross-border transactions to promote international financial cooperation. Although these primary forms of cooperation cannot fundamentally resolve the inherent contradiction between the sovereign currency and the international reserve currency, they can help alleviate the transaction risks caused by the exchange rate fluctuations of the world’s major currencies, and are paving stones on the road to success. Only by taking the practical steps of opening up step by step and through long-term efforts can we win more initiative in developing an open economy.

⑼ What are the main problems and challenges facing the current ideological field

The main problems and challenges facing the current ideological field:

1. Western countries regard the development and growth of our country as a challenge to their values ​​and institutional models, and intensify their ideological and cultural infiltration into our country. The struggles and contests in the ideological field are long and complex.

2. In the face of existing and possible political and ideological conflicts, on the one hand, China should avoid confrontation situations similar to those between the United States and the Soviet Union during the Cold War, and seek more communication and understanding; On the one hand, China should not make naive mistakes, but should be moderately vigilant. This is not only a need to ensure the stable development of the country’s economy and society, but also a warning experience obtained from similar upheavals in the Soviet Union and Eastern Europe and “color revolutions”.

3. Some erroneous views in China appear from time to time. Some advocate Western values, some use the history of the party and the country to talk about things, and some deny reform and opening up in the name of reflecting on reform. Some deny the four basic principles.

4. Under the conditions of profound changes in our society and the continuous expansion of opening up, various social contradictions and problems are superimposed and presented in a concentrated manner, and people’s ideological activities are independent, selective, variable and different. significantly enhanced.

5. The usual method used by Western forces to engage in “color revolutions” is to start with ideology, and start with denying and vilifying the system. This has to make every Chinese person, especially Party members and cadres, be more vigilant. As General Secretary Xi Jinping pointed out in his speech at the Central United Front Work Conference on May 18, 2015: “In today’s world, wars without gunpowder smoke are everywhere in the ideological field, and the battle without guns and guns in the political field has never stopped.”

⑽ Current problems and challenges in building a beautiful China

1. Population problems are prominent. First, the huge population size puts forward higher demands on resources, which intensifies the damage and pollution to the environment. Secondly, the problem of population aging is serious, and the proportion of the youth population is seriously low. This has led to the rapid rise of the old-age dependency coefficient in my country, the intensified pressure on social security, and the prominent problems of medical care and pensions for the elderly.
2. The resource situation is very severe. Although my country has a vast land and abundant resources, due to its large population, the per capita possession of natural resources is far below the world average. The characteristics of my country’s land resources are “one more and three less”, that is, the absolute quantity is large, the per capita possession is small, the high-quality arable land is small, and the developable reserve resources are small. Moreover, with the continuous growth of the population, the land used for industrial and mining, transportation and urban construction continues to increase, and the per capita arable land area continues to decrease.
my country is rich in mineral resources, but its per capita possession is only 58% of the world average. The proportion of large and super-large deposits is relatively small, and there are many lean ores, refractory beneficiation and associated ores, especially iron, copper, and aluminum. Soil, lead, zinc and gold are mostly poor minerals, with a large proportion of difficulty in selecting, and the mining cost is generally relatively high, and the proportion of actual resources available for use is relatively low.
my country is a country with a shortage of water resources, and the per capita water resources are only 2,200 cubic meters. Among the more than 600 cities in my country, more than 400 cities have insufficient water supply, of which 110 cities have serious water shortages, and the total urban water shortage in the country is 6 billion cubic meters. The contradiction between the finiteness of resources and the infinity of people’s needs has become the bottleneck of the harmonious development between man and nature in our country.
3. The environment is deteriorating day by day. �While China has achieved tremendous economic development, it has paid greater resource costs, environmental costs and ecological costs. my country’s economic development is at the expense of massive consumption or even destruction of natural resources. After the reform and opening up, the situation of ecological degradation in my country has not been reversed, but has become more serious. If the current economic development model is continued, the problem will only become more serious.
